Military applications in the laser process, the solid-state lasers can be regarded as a rising star. Until the 1990s, due to the development of laser technology, solid-state lasers only emerge in a variety of military applications, and become the absolute protagonists. Laser range finder is the unit most commonly used in laser systems, they are equipped in the main station tanks, artillery and infantry fighting vehicles superior. Equipment, you can greatly improve the attack hit rate. Compared to the traditional optical targeting equipment, hit rate several times. At present, the laser range finder service most 1.06mm neodymium-doped yttrium aluminum garnet (:) laser range finder. The working voltage of laser pointer is the important parameter of laser pointer .
However, due to long-term use of the solid-state laser is easy to damage the eye mask, eye being turned to the safety of 1.54mm erbium  of the phosphate glass laser. Of course, there are several large-scale use of conventional laser weapons, such as a laser target designator, laser radar, etc. [12]. Laser, said laser anti-missile missile defense or the basic features are: the speed of light with a high-energy laser to destroy the missiles or other running speed of sound flight solid. We can say that this is the LD-pumped solid-state lasers in the world, because it has some outstanding advantages. The working voltage of laser pointer should be included in the instruction of laser pointer .
Using a computer with a standard page description language to explain the difference between this way of reducing the content of the print interpreted as page description file, then page description files to raster image interpretation process, but the computer will print directly to explain the content can become direct printing of raster bitmap, thus greatly reducing the performance of the print controller and memory requirements. Because of its lower requirements for print controller, to some extent reduce the cost of the printer. On the other hand an increase of computer system resources, the printer's performance to some extent depends on the computer's performance. The output of laser pointer is the pulse type.
PostScript and PCL and compared to the standard language, GDI is a non-standard way, the way the printer manufacturer to achieve and interpret the bitmap format is quite different, while the print controller's requirements vary, demonstrated performance are quite different.
